One part of the invention consists .in a'novel closure aflixmg appliance.

the invention consists in a novel combination Another part of of parts whereby on the aflixing having been effected during the pressure stroke of the machine the closure aifixing member or apyield if the container exceeds a certain height, thus to compensate for discrepancies in heights of bottles.

In the drawings,

Figure 1 shows partly in side elevation and partly in section suflicient of a machine embodying the invention to illustrate the same;

Figs. 2 and 3 are upper one of the coacting pressure eifecting the frame by any The means 0 includes a casting (herein- 4-4,' Fig. 1,

means, showing two positions of the parts, the part 0" being removed;

Fig. 4 is a horizontal section on about line certain parts being omitted.

Figs. 5 and 6 are plan views of the closure afiixing appliance and plunger V Fig. 7 is a plan, partly in section, of the part a"; v

Fig. ,8 is a plan, partly in section, of certain parts of the aflixing appliance in the form thereof shown in Fig. 1;

Fig. 9 shows a modified form of the afiixing appliance; and

Fig. 10 is a plan view of certain parts of the aflixing appliance'in the form thereof shown in Fig. 9.

It will be understood that it is immaterial whether the bottle-is elevated or the means carrying the aflixing appliance descends in order to effect afliking.

In the construction illustrated the latter 'isthe condition assumed, the bottle support secured to the frame I) the means a being moved up and down in suitable means.

after termed the abutment member) in two parts,- body part c and front part or cover 0" suitably held together, as by screws d.

. Body part c has vertical grooves e'engaged opposite vertical guiding (g) of one of which is in a plane front elevations of the .3 difference between that of g g at 0 the head m has an inclined face to impinge the abutment v a being suitably of the machine, and

by suitable guldes. (not shown) on the frame, and it is formed with a cavity f open at the front thereof and forming at the front faces 9, the upper portion slightly nearer than the lower portion thereof to the opposite guiding face 9 and joins said lower portion in an inclined cam abutment face h; body part 0 also has a socket 71 extending upwardly from the cavity and the parts a and c' further form together a bearing 7', vertically alined with the socket z. The cover part c" has a vertically inwardly oppn groove is.

member is the aflixmg member, which includes a tubular stem 1 journaled and slidable vertically in the bearing 9' and formed at its upper end with a headm and at its lower end with an enlargement or boss n. The head m bears against the bottom of cavity f, and it projects forward between the I two guiding faces 9 9, its forward portion being about as wide as the distance between 9' 9, so that when it is depressed (Figs. 1 and 2) the aflixing member may rotate in bearing 7' a distance which is equal to. the the spacing of g g and cam abutment face h. The head further has a cylindrical socket 7) opposed to socket 'Z, and reaching forward from said socket to the front face of the head a vertical slot qformed with inclined cam faces 9' and q? facing respectively upwardly and downwardly and pitched oppositely to the abutment faces h and 0. To the boss at are secured the parts having directly to do with the closure aflixing. as will appear.

In the tubular affixing appliance is arranged the plunger 7* having a hardened ferrule 8 to bear on the closures and provided with a cylindrical head t. which fits the socket p and has a forwardly projecting tongue wwhich projects into the slot is and keeps the plunger from. turning; this tongue penetrates theaslot 'qand fits the same and it has on its sides the inclined-cam faces a u" pitched the same as the cam faces q' q" and respectively adapted to wipe against them whenthe plunger is moved vertical relatively to the aflixing appliance (compare Figs. 2 and 3). of the plunger is that shown in Figs. 1 and 2-depressed, and in this position it is held telescoped relation to the abutment The normal position by a spring a interposed between the plunger head If and the top of socket i.

The type of instrumentality directly concerned in the'attaching of the closure to the bottle head will usually afford a throat in which the shaping of the metal of the closure is performed and into or through which the lower end of the plunger projects. lVhen the pressure stroke occurs, as-soon as the bottle and superposed closure have become sufficiently entered into the throat to effect aflixing of the closure to the head the plunger will laave been elevated (relatively) 1 in the affixing appliance .to the position where its cam faces u u respectively register'with the cam faces 9 g and (since the plunger cannot rotate, being held by engagement in the slot is) said appliance will be cammed around on its vertical axis so that it clears the abutment face h, whereupon, being unlocked, the affixing appliance yields with respect to the abutment memer. bearing against cam face g depresses the affixing appliance until the head of the lat ter clears the guiding face 9', whereupon cam face u by wiping over cam face 9 rotates the aflixing appliance back to its original position, abutting abutment face 72. Spring v of course maintains the necessary pressure for. sealing and on the return stroke resets the parts to their normal positions (Figs. 1 and 2). It willbe obvious that bottles of various heightsmay be accommodated, the extent of yield of the affixing appliance being more or less. according to the height of the bottle.

In the construction herein shown and described the lateral shifting of the afiixing affixing member being appl ance to clear the abutment member at is due not only to the camming action of the rising plunger (at u 9'') but to the affixing appliance being normally impelled laterally by the inclined abutment o as an incidentof the bottle-pressing the affixing appliance upwardly, the affixing appliance being free to respond to the camming action of said faces and shift laterally q begin to coinas soon as the cam faces u cide. 1 My invention distinguishes from previous constructions in this I itself shiftable later ally into and out of locking engagement with an abutment member: in previous constructions, as I am advised. the interlock between the abutment and afiixing members has been afforded by a pawl or other third member. It also-distinguishes from prior art known to me in respect to the fact that the shifting as between two abutting members in the strumentality and in order to allow one to clear the other to accomplish the yield is around avvertical axis. r

On the return stroke cam face u' by faces h art by virtue 'ofthe- .being thereupon means to support the affixing in-' an annular expansible throat-forming series of segments 10, an annular cushion means a: for the segments surrounding them and having at least the portion thereof opposite each segment composedof elastic plastic material (the drawing actually showing the cushion means continuously .thereof formed of such material), and an annular unyielding abutment means for the cushion means, as the ,wall of the housing 2, for example, surrounding the same, each said portion beingfree to expand lengthwise of the axis of the throat 'on compression thereof between the segments and abutment means when the former are expanded by the entering bottle head; to afford the freedom to expand stated the means a: is shown in Figs. 1 and 9 as tapering in cross-section, thereby leaving, at '02, spaces above and below into which the plastic material can flow When the compression takes place. It is preferable, though not indispensable, that the three elements (segment series w, cushion w and wall 3 fit each other. As shown in Fig. 8, to give a unitary character to the segments. and cushion. the latter may be surrounded by a metal band 4, and an interlock between band and cushion provided at '3. To prevent the segments pinching the rubber of the cushion, their outer vertical edges may be beveled off, as at 6, Fig. 8: or a metal lining provided, as at 7 Figs. v9 and 10, the same being a strap or band having its ends overlapping each other so as to be expansible.
